What are the problems with sunroofs?

These basic problems are the sunroof issues most commonly encountered by vehicle owners: 1 Mechanical problems . Most mechanical problems, such as breakage or loose glass, can be replaced or repaired with a few hand tools. Fixed-glass sunroofs can often be fixed with nuts and bolts. Urethane-adhesive sunroofs, however, might best be left to the professionals. 2 Sticking, popping, or twisting sunroofs. These issues can be tricky to address. Sometimes, it’s a simple lubrication problem, and greasing the tracks with heavy silicone grease can free up sticky sunroofs and prevent wear. Unfortunately, this maintenance step is often overlooked until it’s too late. Sticking and binding may also be caused by worn or broken cables. The flexible cables mesh with a gear on the motor, but can quickly be ruined if the track is sticking. This is a big repair, and probably not in the realm of DIY auto repair. 3 Inoperable sunroof. If your sunroof is inoperable, there could be an electrical problem at work, such as a blown fuse (possibly related to lack of lubrication), broken wire, or dead switch or motor. Always check fuses first, then whatever you can access easily. The sunroof motor may be difficult to access, but some automakers place them behind overhead consoles, which can be easily removed.

External sunroofs, which are less common than internal sunroofs, sit on top of the roof of the vehicle. Most are glass, but some are textile, and they retract on tracks built into the roof. A third category includes fixed sunroofs, non-moving glass panels designed to let in more light.
